Slow GPS fix with ipod touch with car kit

Jan 5, 2011
Maybe somebody can help me.
My car kit finds very slowly the GPS position for TomTom Navigation software. It may take up to 15-20 minutes!
Once it finds, it works perfectly. If I keep the cradle connected to power for the night, next morning starts to work immediately. If not, it starts with the above mentioned long search again....
The strange thing is that the free TomTom Car Kit Tool App finds almost immediately GPS fix, it shows the satellites channels and the coordinates as I am moving around, but when I quit it and start the TomTom navigation software, it does not get the positions. The same happens with other navigations softwares. I installed a free App called GPS-Status and this also does not get the positions.
Is it possible that the Car Kit Tool App is more sensitive? Uses other approach to communicate with the GPS chip, maybe directly and the TomTom navigation software uses Ipod system functions?
Somebody has any idea?
I also read somewhere that TomTom has a service called QuickGpsFix. Can this be used with the car kit/ipod?

Hi I have exactly the same problem. I also have an IPhone 4 which works perfectly using the TomTom IPhone car kit and TT 1.6. Using the IPod 4 in the TT Car Kit is a nightmare as you have described. I purchased a Bluetooth GPS receiver from GNS. Google GNS 5870 MFI. I tested the Bluethooth receiver with an IPad that I have and TomTom software version 1.6 and it worked perfectly. I also tested with my IPhone 4 and it also worked perfectly. But when I pair it with my IPod 4 and TomTom 1.6 there is a problem. I get the message 'Connect To GPS' but I can still navigate, so it appears the TomTom software sees the Bluethooth GPS signal. My wife took the IPod and Bluetooth receiver to work today, she reports back saying 'Poor GPS reception' which is just crazy! The units are paired and the 'Green Light' on the Bluetooth is solid green indicating a valid GPS siginal.
I came across this last night Issue 84 - btstack - TomTom reports "Connect to GPS" on new iPod Touch 4G - A Portable User-Space Bluetooth Stack - Google Project Hosting
Which is explains the problem I am now having, but the fix here requires the IPod to be jailbroken. In my mind TT 1.6 and IPod just don't work together, but no one will ever admit to that...

Latest update of app yet when I turn it on it never locates the satellites. Half the time it will start tracking and then suddenly tells me to "Connect GPS" which is of course already connected. Not real useful as it is now.

Hi, anyone find the solution for this problem? I'm having the same issue with my TomTom Car Kit for iPod touch. Takes forever to get the fix even on CarKit tool app.

I don't find any fix on internet and this issue is rendering my unit near the unusable! I can't wait 20 minutes to start drive.
